The prostate is a donut-shaped gland approximately the size and shape of a

chestnut

The prostate surrounds the superior portion of the

urethra just inferior to the urinary bladder

The seminal vesicles are paired pouch-like structures approximately 2 inches in length located

posterior to and at the base of the urinary bladder in front of the rectum

The bulbourethral(cowper) glands are paired glands the size of

peas and are located just inferior to the prostate

Testosterone is the

male sex hormone

The part of each testicle that produces testosterone is called the

interstital cells of Leydig

The functions of testosterone include

develop & maintain male sex organs*descent(just before birth) of the testes from the abdominopelvic cavity into the scrotum*broadening the shoulders & narrowing the hips during puberty*Protein build muscles producing muscular bulk/firmness in the physique

Additional functions of testosterone include

Maturation of the spermatozoa*enlargement of the thyroid cartilate(adam's apple)*deepening of the voice*influending aggressive behavior*causing facial-body-public hair to appear*stimulates the sexual drive(libido)

An outpouching of loose skin from the pelvic wall which supports & contains the testes is called the

Prostatic urethra which is surrounded by the prostate*membranous urethra which runs from the prostatic urethra to the penis*spongy or cavernous urethra found inside the penis & terminates at the male urethral orifice(meatus, os)

The penis is designed to

introduce spermatozoa into the femal reproductive tract

The penis consists of the shaft whose distal portion is slightly enlarged called the

glans penis

Covering the glans penis is a section of loose skin called the

prepuce(forskin)

Internally the penis is composed of

three cylindrical masses of spongy tissue containing blood sinus

Sexual stimulation causes the penile arteries to

dilate allowing large quanities of blood to enter the penis

Expansion of the blood sinuses compress the

penile veins

when the penile arteries dilate and the expansion of the sinuses compress the penile veins this causes an

erection

Once sexual stimulation ceases, the penile arteries will

constrict

The penile veins drain the blood and

the erection is lost

The inability to achieve or maintain an erection is called

impotence AKA Erectile Dysfunction(ED)

Impotence(Erectile Dysfunction/ED) can be caused by

Poorly controlled stress*Trauma to the nerves controlling blood flow to the penis*Diabetes Mellitus(DM)*Arteriosclerosis of the arteries that supply blood to the penis*side effects from certain medicaitons such as antihypertensives & antidepressants
